Ujeedada ugu weyn ee daaweynta dusha sare ee saqafka dhismaha waa in la hagaajiyo iska caabbinta miridhku iyo iska caabbinta miridhku iyo in la dheereeyo cimriga adeegga. Kuwa soo socda waa hababka daaweynta ee caadiga ah iyo faa'iidooyinkooda iyo khasaarooyinkooda:
- Galvanizing Kulul-Dip
Habka: Ku quusi qaab dhismeedka birta dareeraha zinc la dhalaaliyay si aad u samayso lakab daawaha zinc-iron ah iyo lakab zinc saafi ah.
Faa'iidada:
- Iska caabin miridhku aad u xoog badan, nolosha iska caabinta daxalka waxay gaadhi kartaa in ka badan 20 sano.
– Looma baahna dayactir ka dib, oo ku habboon bannaanka, qoyaanka ama meelaha daxalka badan leh (sida meelaha xeebaha ah).
- Dahaarka lebbiska ah iyo daboolid dhamaystiran.
Qasaaraha:
- Qiimaha sarreeya iyo habka adag.
- daahan qaro weyn (qiyaastii 80-100μm), taas oo laga yaabaa in ay saameyn ku shirka ee qaybaha saxda ah.
- Daawaynta heerkul sare waxay keeni kartaa wax yar oo birta ah.
- Electro-Galvanizing
Habka: Ku samee lakab zinc ah oogada sare ee birta iyadoo la isticmaalayo koronto.
Faa'iidada:
- Qiimaha hooseeya iyo habka fudud.
- Dahaarka jilicsan iyo muuqaalka quruxda badan.
- Ku habboon bay'adaha daxalka fudud (sida gudaha gudaha ama meelaha engegan).
Qasaaraha:
- Dahaarku waa khafiif (qiyaastii 5-20μm), awoodda ka-hortagga miridhku way ka daciifsan tahay galvanization-ku-kulul.
- Way fududahay in la xoqdo ama la xoqdo ka dib.
– Kormeer iyo dayactir joogto ah ayaa loo baahan yahay.
- Rinjiyeynta
Habka: buufin ka-hortagga daxalka iyo koodhka sare (sida rinjiga epoxy, rinjiga polyurethane).
Faa'iidada:
- Qiimaha ugu hooseeya, dhismo dabacsan, midab la beddeli karo.
- Dayactir sarreeya, fududahay in dib loo rinjiyeeyo ka dib burburka deegaanka.
- Ku habboon mashaariicda muddada-gaaban ama baahiyaha miisaaniyad-hoose.
Qasaaraha:
- Awoodda guud ee ka hortagga miridhku, u nugul fallaadhaha ultraviolet iyo nabaad guurka roobka, waxayna u baahan tahay in dib loo buufiyo 2-3 sano kasta.
- Filimka rinjigu waxa uu leeyahay adhesion daciif ah oo ay fududahay in la diiriyo.
- Dahaarka budada (buufin elektrostatic ah, Dahaarka budada)
Habka: Daahan budada ah ayaa lagu dhajiyaa elektrostatics waxaana lagu daaweeyaa heerkul sare.
Faa'iidada:
- Dahaarku waa cufan, wuxuu leeyahay dhejis adag, wuuna ka adkaysi badan yahay rinjiyeynta buufinta caadiga ah.
- Deegaanka saaxiibtinimo leh (aan lahayn wax dareere ah), oo leh midabyo kala duwan.
- Ku habboon degaannada daxalka dhexdhexaadka ah.
Qasaaraha:
-Qiimaha ayaa ka sarreeya rinjiyeynta buufinta caadiga ah, laakiin ka hooseeya galvanization.
- Daawaynta heerkulka sare waxay keeni kartaa qallafsanaanta birta.
- Way adag tahay in la hagaajiyo ka dib burburka degaanka.
Soo jeedinta xulashada
Bey'ad aad u daxalaysa (sida aagagga xeebaha, dhirta kiimikada): galvanization-ku-kulul ayaa la door bidaa.
Bey'adda caadiga ah ee dibadda: galvanization-ku-kulul ama buufin.
Baahida muddada-gaaban/qiimaha jaban: rinjiyeynta buufinta ama korantada.
Shuruudaha ilaalinta deegaanka ee sarreeya: buufinta.
Taxadarka
– Si fiican uga saar miridhka ka hor daawaynta dusha sare (sida ciid-qarxinta, qajaarka).
- Habab kala duwan ayaa loo isticmaali karaa isku darka (sida galvanizing + rinjiyeynta buufinta si kor loogu qaado ilaalinta).
- Kormeer iyo dayactir joogto ah, dayactirka waqtigeeda ee daaha burburay, kana fogow faafidda miridhku.
